摘要:

为了改善地质聚合物(GP)的电学性能,以酸化碳纳米管(CNTs)为增强剂、高岭土为原料、水玻璃和氢氧化钠为碱激发剂,制备了碳纳米管/地质聚合物复合材料(CNTs/GP)。采用红外光谱仪、扫描电子显微镜及X-射线衍射仪表征复合材料的组成和微结构;采用热重分析仪测试复合材料的热稳定性;采用抗压强度测试和四探针法研究CNTs对复合材料的抗压强度和电导率的影响。CNTs的添加未影响GP的凝胶相结构。但CNTs与基体之间差的相容性在复合材料里产生了大量孔隙,降低了复合材料的抗压强度。CNTs的添加显著改善了GP的导电性,当CNTs的质量分数为5%时,CNTs/GP的电导率为8.6×10-6 S/cm。因此,适量添加CNTs,能使GP在保持较高的抗压强度的同时,具有较好的导电性能,可以应用于抗静电材料领域或电子元器件领域。
Abstract:

To improve the electrical properties of geopolymers (GP),carbon nanotubes/geopolymer composites (CNTs/GP) were prepared using kaolin as raw material,water glass/sodium hydroxide as alkali activator,and acidified carbon nanotubes (CNTs) as reinforcing agents. The composition and microstructures of the composites were characterized via infrared spectroscopy,scanning electron microscopy and X-ray diffraction. The thermal stability of the composites was investigated with the thermogravimetric analysis. And the influences of CNTs on the compression strength and electrical conductivity of the composites were investigated via compression strength testing and four-probe method. The results indicated that the addition of CNTs did not affect the gel-structure of the GP,while induced plenty of pores in the CNTs/GP due to the poor compatibility between CNTs and the matrix,thus reducing the compressive strength of the composites. Significantly,the addition of CNTs improved the electrical conductivity of GP. When the mass fraction of CNTs was 5%,the electrical conductivity of CNTs/GP was 8.6×10-6 S/cm. The addition of proper amount of CNTs made GP possess high antistatic performance and maintain high compressive strength. The composite could be applied in the field of antistatic materials or electronic components.
